On my main computer that I have Spiceworks installed, I do have the inventory configured, but I can't connect to my laptop.

this is my home network, and I am trying to learn how this all works. I even tried by disabling firewalls... other than that I have read all the documents and tried changing all the settings, but maybe I misread something so I am not clear on where to start looking.

Make sure that you have an account with the Admin credentials needed and that you have the firewall open to have the scan allowed...we had this on something here at work...finding out that the scan account wasn't allowed to index said device.
